DESICCANT-BASED PRECONDITIONING TECHNOLOGY SATISFIED THE REVISION NORM

摘要

The China Standard GBJ 19-1987 "Design Norm of Heating, Ventilation and Air Conditioning" has been now revising. It will increase fresh air requirement and control indoor relative humidity on a lower level. The huge additional cooling load will be added in the air conditioning system especially in east and south China. A desiccant-based preconditioning technology was developed in our research, which will be promoted in this country to isolate and solve this problem in office buildings at reasonable cost.
